It allows the observation of samples without losing temperature.

SUITABLE FOR EVERY LABORATORY NEED The AREX magnetic stirrer is a great tool for basic laboratory ap (more)plications, but with the optional VTF system, which allows you to thermoregulate the sample up to 300°C with an accuracy of ± 0.5°C, it will be possible also use it for more complex applications. RESISTANCE, SAFETY AND PERFORMANCE The plate of the AREX 5 Velp model is IP42 certified and is made of aluminum alloy coated with a ceramic layer, which guarantees protection from scratches and chemical agents, making it very resistant and easy to clean. It is therefore preferred in laboratories where acids, bases and solvents are used. Safety circuits and overtemperature protection guarantee complete protection for the operators. Two light indicators inform the user when the heating function is active. Even when the instrument is switched off, an indicator light remains on until the plate temperature drops below 50°C. The plate structure and the insulating disc protect the internal parts and ensure high resistance to the most demanding laboratory environments and applications, for example when working with cold fluids (below 0°C). AREX 5 is designed to last over time and like most Velp products it is guaranteed for 3 years. PRECISE SHAKING ARE 5 is equipped with a powerful brushless motor for daily applications, being able to agitate up to 20 liters (H2O). It is also equipped with SpeedServo™ technology, which allows the speed to be kept constant even when the viscosity of the sample varies. APPLICATIONS ARE 5 is the ideal solution for temperature sensitive applications in many industrial, research and academic laboratory sectors. THE AREX PANEL: BEAUTIFUL AND SIMPLE TO USE By turning the left knob it will be possible to adjust the temperature up to 310°C, while with the right one it will be possible to set the stirring speed from 100 to 1500 rpm. COMPARISON TABLE OF THE NEW VELP SERIES 5 MAGNETIC STIRRERS:

AREX 6 by Velp Scientifica The central button activates the heating of the plate only after pressing (more) it, avoiding involuntary switching on. The safety icon informs the operator that the plate is at temperature, preventing possible burns. It will remain illuminated until the temperature is below 50°C. The knobs allow precise speed and temperature regulation with new ergonomics and greater sensitivity. CerAlTop™, High Resistance The CerAlTop™ plate, made of aluminum alloy covered with a ceramic layer, guarantees a homogeneous and fast heat transfer over the entire surface. Furthermore, the thin ceramic layer protects the straightener from scratches and chemicals. UNPRECEDENTED PERFORMANCE The brushless motor allows you to shake up to 20 liters at an adjustable speed from 30 to 1700 rpm. Thanks to the SpeedServo™ system, the speed is kept constant even when the viscosity varies. The Alnico magnet guarantees homogeneous agitation, even in the peripheral areas of the plate and a powerful magnetic coupling between motor and stir bar, a very important aspect when using accessories. MAXIMUM INSTRUMENT PROTECTION AREX 6 is an IP42 product designed to guarantee years of use and resistance in the laboratory. The structure and materials protect the internal parts of the instrument from possible damage. AREX 6 is guaranteed for 3 years. The silicone cover ensures further protection of the instrument from possible spills or splashes. Digital thermoregulation with VTF By connecting VTF digital thermoregulators, your AREX 6 transforms into a superior tool, with a built-in timer to schedule activities. The thermoregulator is ideal for multiple applications and meets the most demanding requirements in terms of precision, reliability and flexibility of use thanks to the innovative FUZZY LOGIC Technology. Automatically adapts thermoregulation to various factors such as power, load and heat dispersion. The VTF guarantees premium performance in terms of temperature control: it allows better alignment with the set temperature (with an accuracy of ± 0.5 °C.) and less initial 'overshoot' (initial discrepancy compared to the set temperature). Furthermore, VTF is equipped with a system to simplify installation on the support rod and facilitate positioning of the Pt100 probe in the most commonly used containers. The two clamps allow height adjustment while a sliding clamp allows horizontal adjustment. ACCESSORIES OIL BATH AND HEATING MANTELS REPLACED WITH SPHERICAL CAPS The new Spherical Caps are the perfect solution for replacing oil baths and heating mantles. Furthermore, they adapt perfectly to both the 135 mm plate diameter and the shape of the tubes allowing a fast heat transfer from the plate to the tube. To increase protection and reduce thermal dispersion, VELP has designed the new PTFE Covers. GREATER VERSATILITY The MultiAlublock™ and the new MonoAlublock™ made of aluminium, are ideal for carrying out numerous stirring and heating analyses, reducing time and space in the laboratory. - MonoAlublock™ are the ideal solution for all those applications that require analysis in tubes of the same size. - MultiAlublock™ are modular and of different types to support various tube sizes. Thanks to their modularity, it is possible to choose the mix that best suits your needs
